I guess I'm a little confused on this topic. With respect to SBIG cameras, they do not seem to have any hardware support that allows flooding the CCD prior to new exposures. In this case, most cameras attempt to flood the sensor with Near Infrared light in order to achieve the same effect. Do you know how CCDOPS handles this?

Sure. The new SBIG driver definitely references RBI, but it is not entirely clear how to use it from the docs. I'll reach out to Tim and do some digging. It's possible that we are expected to just use normal camera routines to pre-flash and then throw that data away after it is read, but I don't know for sure.
